Your legal rights depend on what state you live in

What does the letter say? Does it give a reason you have to leave, or does it just tell you to get out?

Unless you have done something to violate the terms of the lease, the landlord does not have the right to end your tenancy early. That is one of the advantages of having a one year lease--you know that you'll have a place to live for a year as long as you pay your rent and follow the rules.

If you've done something to violate the lease then the landlord does have the right to terminate it. Give us more info.
